Despite the fact that Federal legislation (the CANSPAM act) made it illegal, harvesting email addresses from the web using automated robots remains alive and well.
Spammers who need fresh email addresses release software spider programs that comb the Internet and suck email addresses off Web pages, guest books, and anywhere else you might post your email address.
Once they get your email address, spammers will trade it around like 5th graders with a new pack of Pokemon cards at recess and you can expect the avalanche of email to begin flooding your inbox.
In order to combat this still rampant practice of stealing email addresses from websites and sending people email they don't want, the following tips should help protect you.
Break It Up
Obviously the best way to avoid getting picked up by an email harvester is not to post your email anywhere on anyone's website (including your own).
If the only way someone can get your email is if you give it to them, that creates a similar situation to operating with an unlisted phone number.
If telemarketers can't get your phone number, they can't call.
If you must post your email address, post it in a way that a robot won't recognize it as an email address. Instead of posting YOURNAME@YOURDOMAIN.COM, you can put YOURNAME (AT) YOURDOMAIN.COM and then, in parenthesis, put (replace AT with @ to email me).
Though it seems like an extra step for legitimate email, you'll find it a very effective technique.
Use An Image
Currently, online spiders (ANY spider, including search engines) cannot read text that appears in a graphic or picture. If you must display an email address on a page, then do it by typing your email address into your favorite graphics program and saving the image as a .gif or .jpg. Then post the image onto your web page so people can see the email, but spiders cannot. This too creates an extra step for people because they must type in your email address, but it's an effective solution if you must display an email address on your own website.
Use An Email Form
Another way to cut down on spam originating from your own website is simply not to display an email at all.
Instead, allow customers and prospects to contact you through a form where they fill in fields, click a button, and your website emails you their message.
A note of caution: make sure the form script you use does not keep your email address visible in the form code.
If the form code contains the email address, spam robots can find it even though you don't see it on the page.
Make It Hard To Guess
Sometimes you'll get unsolicited email because a spammer guessed your email address.
It's not a far stretch to imagine that someone probably has the email Jim@yourdomain.com, so spammers will do a "dictionary" attack on common usernames.
One way to defeat this is to place a "dot" (.) in your email address, such as Jim.Edwards@yourdomain.com. The dot makes it virtually impossible for spammers to guess your email address.
